More than $44 Million of upgrades to the Outer Harbor and Grange rail lines have been completed in the past three weeks, including a new bridge taking the rail line over South Road at Croydon, supporting hundreds of jobs.

“More than 150 Grange and Outer Harbor train services pass through the level crossing at South Road every weekday, causing substantial disruptions to the flow of traffic on this major arterial road and freight route.” Minister for Transport and Infrastructure Stephen Mullighan said.

More than 110 people worked on the installation of the 720-tonne steel bridge spanning South Road as part of the $896 Million Torrens Road to River Torrens Project.

“The overpass and train line were able to be opened on schedule thanks to the hard work of more than 110 dedicated staff who worked around the clock to complete the works.” Mr. Mullighan said.

Data from the Traffic Management Centre shows drivers travelling south between Hawker Street and Port Road are already saving up to three minutes in travel time.

The bridge was fabricated by local company Samaras Group and features approximately 270 tonnes of Arrium steel for pile reinforcement, rail tracks and concrete deck reinforcement.

“By using prefabricated bridge sections and installing them in three separate sections, the T2T Alliance has been able to minimise disruption to services on the Outer Harbor and Grange lines.” Mr. Mullighan said.

In all, more than 260 people were employed on a number of projects as part of a blitz of works on the Outer Harbor and Grange lines to maximise the closure.

Those projects include:

  • An estimated $1.5 Million of preliminary works on the $258 Million Torrens Rail Junction, including survey and service ‘depthing’ along the rail corridor and relocation of the boom gates on Park Terrace
  • $4 Million upgrade to the 105 m Port River rail bridge, extending its life by approximately 75 years
  • $150,000 on upgrades to the Grange, Taperoo, Peterhead, Ethelton, Cheltenham, Croydon and West Croydon stations, which will include repainting, installation of new bins and replacing damaged signs.
  • $1.8 Million replacement of the train tracks between Woodville Station and Port Road, with the City of Charles Sturt spending $550,000 on drainage works beneath the railway lines at Port Road
  • $500,000 of Outer Harbor line level crossing upgrades at Harris Street, Hargrave Street and Gedville Road
  • $1.1 Million to replace signalling cables along sections of the rail corridor

 

Background

Closure of the Outer Harbor and Grange rail lines was timed to coincide with the lowest patronage period of the year and substitute buses operated during the closure.

$896 Million Torrens Road to River Torrens Project is jointly funded by the State and Commonwealth Governments on a 50:50 basis.
